Faraday's Second Law
It states that,
“When the same quantity of electricity is passed through different electrolytes, the masses of different ions liberated at the electrodes are directly proportional to their chemical equivalents (Equivalent weights).” i.e.,
Thus the electrochemical equivalent (Z) of an element is directly proportional to its equivalent weight (E), i.e.,
where, Faraday constant
So, 1 Faraday = 1F =Electrical charge carried out by one mole of electrons.
1F = Charge on an electron × Avogadro's number.
